The NANO TEC technology works by evenly distributing nano-sized particles in the vacant space between carbon fiber bundles, this highly increases the overall stiffness of the carbon composite fibers, and reduces the distortion of the frame.
The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
PYROFIL carbon fiber and its composites, are advanced high-performance materials from Japan. The characteristic of high intensity bonds ultra-light offer racket excellent shock-absorption and enhance handling in every single game.
Inspired by military helicopter, multi-layered structure made by carbon fiber and composites, minimize material size, reinforce handling feel and performance at a critical standard.
The Whipping Enhancement System incorporates a softer material in a specific part of the shaft near the throat, enhancing racket-head acceleration in a “whipping” style which helps to create steeper and quicker attacks with satisfying control.
Configure and combine white wood, carbon fiber, and resin through foam moulding technique, creating a standardized design. This newly developed material can effectively increase precision, weight, and performance without the tendency to absorb water and deform, enabling better hitting experience and stability.
The compound frame design can be divided into three major parts: The upper section is made with fan-shaped structure to lower wind resistance and accelerate each swing. The Compound-Sword structure in the middle section is designed to lighten the filler and enable fast rebound. Finally, the lower section is built in airfoil structure to lower wind resistance and keep excellent anti-torsion performance in a 'whipping' style which helps to create steeper and quicker attacks with satisfying control.
